Testing it further (but not in a completely) with gfontsampler, it seems that Freetype has problems with faked acute accented characters. With all Latin vowels (capitals or not) the accent is displayed wrong, excepting the iacute, that has the letter wrong displayed.

This bug report is incomplete, please provide the following if you don't want me to delete it:

- exact version of the font file, + a link or pointer to it
- point size, resolution, hinting mode, glyph indices or character code information
- simple steps to reproduce the problem, preferabbly with ftview

The latest version (0.50) of Legendum doesn't contain
glyphs for á and í! Is it possible that they are
replaced with glyphs from another font? I'm not
sure whether Firefox is sophisticated enough to check
that e.g. á can be composed with `a' and a non-spacing
accent (which Legendum provides)...
